Leap year check

A year is a leap year in the Gregorian calendar when it is divisible by 4, with one exception and one exception to that exception: a year divisible by 100 is not a leap year unless it is also divisible by 400. 2101 is not divisible by 4 (2101 ÷ 4 = 525.25), so it cannot be a leap year. The nearest leap years are 2096 before it and 2104 after.
2101 has no February 29, February ends on the 28th. The closest leap day is in 2104, when February 29 falls on a Friday. If you are counting toward a leapling birthday or a date-sensitive deadline, that 2104 leap day is the one to watch.
2101 runs 365 days, or 52 full weeks plus 1 day. The leap year before 2101 was 2096 and the next one is 2104, keeping the familiar four-year rhythm. To do date math across 2101, counting days to a deadline, an age, or an anniversary that crosses a leap day, use the days-between calculator, which handles leap days automatically.
